It is illustrated thatall applications running on computing equipment and the computingequipment may be parts. One or more parts may reside in a process and/oran execution thread, and the parts may be located on a computer and/ordistributed between two or more computers. In addition, these parts maybe executed from various computer-readable media on which various datastructures are stored. The parts may communicate through local and/orremote processes according to, for example, signals with one or moredata groups (for example, data from two parts interacting with eachother in a local system, a distributed system and/or a network, forexample, the Internet interacting with another system through a signal).

It should be understood that the technical solutions of the embodimentsof the disclosure may be applied to various communication systems, forexample: a GSM, a CDMA system, a WCDMA General Packet Radio Service(GPRS) system, an LTE system, an LTE Frequency Division Duplex (FDD)system, LTE Time Division Duplex (TDD), a Universal MobileTelecommunication System (UMTS), a Worldwide Interoperability forMicrowave Access (WiMAX) communication system and a future 5Gcommunication system.

Each embodiment in the disclosure is described in combination with aterminal. The terminal may communicate with one or more core networksthrough a Radio Access Network (RAN), and the terminal may refer to UserEquipment (UE), an access terminal, a user unit, a subscriber station, amobile radio station, a mobile station, a remote station, a remoteterminal, mobile equipment, a user terminal, wireless communicationequipment, a user agent or a user device.

Each embodiment in the disclosure is described in combination with abase station. The base station may be equipment configured tocommunicate with the terminal equipment, and for example, may be a BaseTransceiver Station (BTS) in a GSM or CDMA, may also be a NodeB (NB) ina WCDMA system, and may further be an Evolutional Node B (eNB or eNodeB)in an LTE system. Or, the base station may be a relay station, an accesspoint, vehicle-mounted equipment, wearable equipment, network-sideequipment in the future 5G network and the like.

FIG. 1 is a schematic flowchart of a resource indication method 100according to an embodiment of the disclosure. As illustrated in FIG. 1,the method 100 involves a base station and a terminal, and includes, butnot limited to, the following operations.

In S110, the base station generates a resource indication channelaccording to a setting of a system and a current resource allocationcondition. The resource indication channel is configured to indicate afirst time-frequency resource and communication parameters for using thefirst time-frequency resource, and the resource indication channeloccupies a second time-frequency resource. As schematically illustratedin FIG. 2A, the first time-frequency resource R includes the secondtime-frequency resource r (illustrated by a shadow part), that is, atime-frequency range occupied by the second time-frequency resource iswithin a time-frequency resource occupied by the first time-frequencyresource.

It should be understood that the second time-frequency resource r of theembodiment of the disclosure may include at least one time-frequencyunit. When the second time-frequency resource r includes only onetime-frequency unit (for example, a first time-frequency unit r-1illustrated in FIG. 2A), a time range corresponding to the firsttime-frequency unit r-1 is a time point set by the system, and afrequency range corresponding to the first time-frequency unit r-1 is afrequency raster (which may usually be recorded as f_(R), for example,f_(R)=K×100 KHz, K being a factor related to a band) set by the system.

When the second time-frequency resource r includes multipletime-frequency units, the first time-frequency unit r-1 may includeinformation indicating that the resource indication channel is extendedfrom the first time-frequency unit r-1 to occupy multiple time-frequencyunits of the second time-frequency resource (for example, the firsttime-frequency unit r-1, the second time-frequency unit r-2 and thethird time-frequency unit r-3 illustrated in FIG. 2B), i.e., extended tooccupy information of the second time-frequency resource r. Here, thefirst time-frequency unit r-1 may be extended towards the time range,and may also be extended towards the frequency range, which will not belimited in the embodiment of the disclosure. The time rangecorresponding to the first time-frequency unit r-1 is still the timepoint set by the system, and the frequency range corresponding to thefirst time-frequency nit r-1 is still the frequency raster set by thesystem.

In addition, the resource indication channel is distributed on someresources with relatively fixed time ranges and frequency ranges, andthe resource indication channel occupies relatively fewer time-frequencyresources for indicating allocation of wider time-frequency resources inthe vicinity and communication parameters. On the basis of thecharacteristics of the resource indication channel, the resourceindication channel may be vividly called as an “anchor channel”. Besidesthe examples, illustrated in FIG. 2A to FIG. 2I and FIG. 3, that thesecond time-frequency resource is in the first time-frequency resource,the time-frequency range of the second time-frequency resource occupiedby the resource indication channel may also not be in the time-frequencyrange occupied by the first time-frequency resource, which will not belimited in the embodiment of the disclosure.

It should be understood that the first time-frequency resource indicatedby the resource indication channel of the embodiment of the disclosuremay also be considered to be a time range and a frequency rangeadministered by the resource indication channel. A frequency rangeadministered by a resource indication channel is N (N is more than orequal to 1) times of a frequency raster, and a time range administeredby the resource indication channel is one or more fixed time units orconfigurable time lengths (which may be indicated in the resourceindication channel). The system may predetermine that, if N is largerthan 1, the terminal is not required to search for another resourceindication channel from other N−1 frequency rasters in the time rangeadministered by the resource indication channel, so that efficiency ofexchanging the resource allocation condition between the base stationand the terminal may be improved.

It is important to note that the first time-frequency resource Rindicated by the resource indication channel in the embodiment of thedisclosure may preferably include all resource units in a certain timerange and a certain frequency range, i.e. a regularly shaped regionillustrated in FIG. 2A and FIG. 2B; and the first time-frequencyresource R may also be obtained by reducing some resource units in allthe resource units in the certain time range and the certain frequencyrange, i.e. an irregularly shaped region illustrated in FIG. 2C. Inaddition, the second time-frequency resource r may be at an edgelocation of the first time-frequency resource R (as illustrated in FIG.2A to FIG. 2G), and may also be at a non-edge location of the firsttime-frequency resource R (as illustrated in FIG. 2H).

The resource indication channel may be configured to indicate that thefirst time-frequency resource is not used, that is, the resourceindication channel may further be configured to indicate a region wherethe resource is not used, as illustrated in FIG. 2I. For example, it maybe applied to a scenario of interference coordination between cells andthe like. Using or not using the resource may be distinguished bysetting values of indicating bits in the resource indication channel.

In the embodiment of the disclosure, at least one first time-frequencyresource corresponding to at least one resource indication channel mayform a cell. When the cell includes multiple first time-frequencyresources corresponding to multiple resource indication channels, themultiple first time-frequency resources are not completely the same interms of at least one of time ranges and frequency ranges. For example,as illustrated in FIG. 3, the cell includes three first time-frequencyresources corresponding to three resource indication channels, includinga first time-frequency resource S (corresponding to a resourceindication channel s), a first time-frequency resource T (correspondingto a resource indication channel t) and a first time-frequency resourceU (corresponding to a resource indication channel u) respectively. Timeranges of the first time-frequency resource S and the firsttime-frequency resource T are different, and frequency rangescorresponding to the first time-frequency resource S and the firsttime-frequency resource U are different. Therefore, the solution of theembodiment of the disclosure may break limits of occupation of fixedcontinuous bandwidths by cells and/or carriers in the related art, andmay further allocate time-frequency resources more flexibly, improveperformance and applicability of the wireless communication system andimplement optimal utilization of the resources.

In the embodiment of the disclosure, the communication parameters mayinclude a cell ID to identify the cell to which the first time-frequencyresource corresponding to the resource indication channel belongs. Thecell ID may be a 32-bit string. In the embodiment of the disclosure, theresource indication channel may include the complete cell ID, and mayalso include part of the cell ID (for example, including 16 bits), andthe other part of the cell ID is transmitted in another resourceindication channel, or sent through additional dedicated signaling ormessage. Of course, in the embodiment of the disclosure, the cell ID mayalso completely not be transmitted through the resource indicationchannel, but is notified to the terminal in another manner, which willnot be limited in the embodiment of the disclosure.

In the embodiment of the disclosure, the communication parameters mayinclude at least one of a multiple access technology used for the firsttime-frequency resource, a duplex manner used for the firsttime-frequency resource, a communication mode used for the firsttime-frequency resource and basic physical parameters corresponding tothe multiple access technology used for the first time-frequencyresource.

Wherein, the multiple access technology used for the firsttime-frequency resource may include at least one of: for example, anOrthogonal Frequency Division Multiplexing (OFDM) technology, aSingle-Carrier Frequency-Division Multiple Access (SC-FDMA) technology,a simple Frequency Division Multiple Access (FDMA) technology, a CDMAtechnology and the like. A time-frequency resource allocation andindication solution of the embodiment of the disclosure may allowvarious multiple access technologies in the system to flexibly coexist.

When including the multiple access technology used for the firsttime-frequency resource, the communication parameters may furtherinclude the basic physical parameters corresponding to the multipleaccess technology. In a specific example, the first time-frequencyresource uses the OFDM technology, its basic physical parameters mayinclude a subcarrier spacing on a frequency domain, a Cyclic Prefix (CP)length, a Transmission Time Interval (TTI) length on a time domain andthe like.

The duplex manner used for the first time-frequency resource may includeFDD, half FDD, TDD, full duplex and the like.

The communication mode used for the first time-frequency resource mayinclude a communication from the base station to the terminal, aDevice-to-Device (D2D) communication and the like.

In the embodiment of the disclosure, the communication parameters of theresource indication channel may further include control channelinformation carried in the first time-frequency resource. For example,the control channel information may include at least one of BCHinformation, MIB information, a PCH, downlink common control channelinformation, downlink dedicated control channel information,self-contained mode information, uplink random access channelinformation and uplink control channel information.

The communication parameters may include information about whether thereis a BCH or MIB in the first time-frequency resource or not. Generallyspeaking, there is at least one BCH or MIB in a cell, and in each firsttime-frequency resource of the cell, there may be a BCH or an MIB, andthere may also be no BCH or MIB.

The communication parameters may include information about whether thereis a PCH in the first time-frequency resource or not.

The communication parameters may include information about whether thereis a downlink common control channel in the first time-frequencyresource or not, and if there are downlink common control channels, thecommunication parameters may further include a time-frequency locationof a first downlink common control channel, and the time-frequencylocation may be indicated by an offset relative to the resourceindication channel.

The communication parameters may include information about whether thereis a downlink dedicated control channel in the first time-frequencyresource or not, and if there are downlink dedicated control channels,the communication parameters may further include a time-frequencylocation of a first downlink dedicated control channel, and thetime-frequency location may be indicated by an offset relative to theresource indication channel.

For a TDD system, the communication parameters may further includeinformation about whether the first time-frequency resource adopts aself-contained mode or not. The self-contained mode refers tosimultaneous inclusion of a downlink and an uplink, and downlinktransmission within the same time range is fed back in an uplink.

The communication parameters may include information about whether thereis an uplink random access channel in the first time-frequency resourceor not, and if there are uplink random access channels, thecommunication parameters may further include time-frequency locationsand number of the random access channels, and the time-frequencylocation may be indicated by an offset relative to the resourceindication channel.

The communication parameters may include information about whether is anuplink control channel in the first time-frequency resource or not, andif there are uplink control channels, the communication parameters mayfurther include time-frequency locations and number of the uplinkcontrol channels, and the time-frequency location may be indicated by anoffset relative to the resource indication channel.

It should be understood that contents of the resource indication channelof the embodiment of the disclosure are not limited to the contentslisted above, and according to a system requirement, the resourceindication channel may further include another related communicationparameters, which will not be limited in the embodiment of thedisclosure.

When the cell where the first time-frequency resource is locatedincludes multiple resource indication channels, a last resourceindication channel of the cell may include information indicating thatthe resource indication channel is the last resource indication channelof the cell to enable the terminal to stop searching for resourceindication channels, so that performance and efficiency of the systemmay be improved. The resource indication channel may be indicated to bethe last resource indication channel of the cell in an explicit manner.For example, an identification bit is set, and whether it is the lastresource indication channel or not is distinguished according to a valueof the identification bit. The resource indication channel may beindicated to be the last resource indication channel of the cell in animplicit manner. For example, a specific characteristic sequence (forexample, a sequence with a specific difference of cyclic shift spacingsfrom a root sequence) is used in the resource indication channel toimplicitly indicate that it is the last resource indication channel.There are no limits made to a specific implementation mode in theembodiment of the disclosure.

When the cell where the first time-frequency resource is locatedincludes multiple resource indication channels, a non-last resourceindication channel of the cell may include a time range and a frequencyrange configured to indicate a next resource indication channel in thecell to enable the terminal to quickly find the next resource indicationchannel, so that the performance and efficiency of the system may beimproved.

It should be understood that the time range and frequency rangeindicating the next resource indication channel may implicitly indicate.For example, a default form may be adopted, and the next resourceindication channel is determined to be on a next time unit of the samefrequency raster after the first time-frequency resource as a default.But the embodiment of the disclosure is not limited so. The time rangeand frequency range indicating the next resource indication channel mayalso explicitly indicate. Particularly when the first time-frequencyresource administered by the resource indication channel is irregular, alocation of the next resource indication channel may be directlynotified to the terminal in an explicit indication manner.

After the base station generates the resource indication channel inS110, in S120, the base station sends the resource indication channel tothe terminal. Correspondingly, the terminal receives the resourceindication channel sent by the base station.

In the embodiment of the disclosure, preferably, the resource indicationchannel is sent in a simple single-carrier manner, i.e. anon-multi-carrier manner such as a non-OFDM manner. In addition,preferably, Multiple-Input Multiple-Output (MIMO) technology may not beused, but using a multi-antenna transmit diversity technologytransparent to the terminal or enabling the terminal to perform blinddetection. There are no limits regarding whether to send the resourceindication channel by virtue of the abovementioned manner or not in theembodiment of the disclosure. Moreover, preferably, the base station maymodulate the resource indication channel in a modulation manner presetby the system. The terminal quickly demodulates according to the presetmanner. The base station may further set a characteristic sequence inthe resource indication channel, and the characteristic sequence isconfigured to indicate that the current channel is a resource indicationchannel to enable the terminal to quickly and accurately find theresource indication channel.

Relatively basic parameters are used for sending when the resourceindication channel is sent by the abovementioned measures, so thatdetection complexity of the terminal may be reduced, the terminal mayquickly and accurately find and demodulate the resource indicationchannel, and system efficiency may be improved.

The characteristic sequence included in the resource indication channelmay also be configured for time and frequency synchronization, or mayrepresent (all or part of) the cell ID. An M sequence or anothersequence with high orthogonality (autocorrelation and cross correlation)may usually be used. The same root sequence and/or homologous sequencesacquired in a manner of cyclically shifting the root sequence and thelike may be used for different resource indication channels in the samecell.

In the embodiment of the disclosure, before the base station sends theresource indication channel to the terminal, the base station mayfurther set a guard band for the resource indication channel. For thecondition that the resource indication channel is located on an edge ofa total available band, an out-of-band radiation index should beconsistent with a local supervision requirement. For the condition thatthe resource indication channel is located in a system band, theout-of-band radiation index should be consistent with an in-band mutualinterference requirement.

It should be understood that, in the embodiment of the disclosure,different cells may stagger sending patterns of resource indicationchannels in terms of time or frequency to avoid mutual interference.Under such a condition, a certain time coordination relationship isrequired to exist between the cells.

In S130, the terminal determines the first time-frequency resource andthe communication parameters for using the first time-frequency resourceaccording to the resource indication channel.
